[arin-ppml] The non-deployment of IPv6

I'm with a small content provider.

At the moment, I don't see us moving any of our sites to IPv6 until
multihoming is realistic option.
The costs aren't an issue, the code changes and config updates are
relatively minor, but lack of multihoming options for sites that only
need an IPv4 /24 to advertise is a blocker.

I see that there are some new (this year) Shim6 RFCs from the IETF.  
Seems unlikely that there will be any real solutions until that effort
is finally dropped.

I agree that looks like a lot of time, but there's quite a few
assumptions in such an estimate and it could move up very quickly.
Additionally, there will be an increasing number of clients which will
attempt to connect via IPv6 *first*, so you actually are impacting your
performance if you don't do IPv6 soon.

as a proxy for my 4 machines and allow them to communicate with IPv6

Does your present firewall device support IPv6 NAT today?   In
discussion this situation with other organizations, I'm generally
finding that routers, firewalls, and load-balancers aren't what are not
what breaks, but instead their tools such as help-desk system and
configuration generators which simply don't know IPv6.  Finding these
issues is a great reason to experiment with at least one public facing
IPv6 server sooner rather than later.
